The is pivotally secured at a to the frame of the first group on the right hand has the keys device;-and O is a spring which throws the from 1 to 5 placed in the lower bank and the engaging cross-bar into contact with the rear rest in the upper bank. The central group supporting-rods.

1 are a vertical series of. registering supperting-rodsone for each lever. These rods are supported upon the lovers in front. of the supporting-rods .l l and pass through suitable slots in the guide-bearings l1 1, and the upper end of each of. these supporting-rods I carries a rack-pawl (.2, hinged to the supporting-rods, parallel thereto, by means of the links R R, and resting with its lower end upon a fixed stop S, which supports the pawl with the links extended at right angles to the supporting-bar. The mmiberot' cogs or teeth on. each rack-pawl corresponds to the numerical value of each lever, by which it is actuated, and thus they form three groups,in conformity with the three groups oi. levers.

T, T, and T are three like serrated rollers journaled transversely in suitable bearings in axial line with each other and indepemlently rotatable. These rollers are jourmiled in proximity to the rack-pawls (,2, so that when i the latter are elevated by the action of the levers (1 they will actuate the rollers by the engagement of their respective cogs or teeth. The roller T is adapted to be operated by any one of the rack-pawls belonging to the first group of levers on the right-hand side. The roller T is adapted to be operated by any one of: the rack-pawls belonging to the central. group of levers, and the roller T is'adapted to be operated. by any one of the rack-pawls belonging to the left-hand group of lovers.

The .rack-pawls Q are only adapted to engage and operate the rollers T, T, and 71. in their upward movement, as in the downward movement they withdraw out of cngagenicut therewith, owing to the manner of securing them, as shown in Fig. To prevent any accidental turning of the rollers each pro vided with a suitable spring back-stop U. The amount of movement imparted to the roller T, T, and T respectively, depends upon the number of cogs belonging to the rack-pawl by which it happens to be actuated, and to adjust said movement correctly the rack-pawls strike at the end of their upward movement against a series of set-screws Y, one for each rack-pawl,adjustablysecured in a cross-bar above the .raek-pawls.

\V is a swinging crank arm or knockcr ex tending with its free end in proximity to the engaging-bar M. The inner end. of the arm of the knocker is secured to a crossbar \W, the ends of which are secured to hangers \V, by means of which the knocker is suspended between the'sides of the frame.

\V is its actuating-striker arm, which is pivotally secured parallel to the vertical. supporting-bar W by the links ll. The lower end of the supperting-l.)a|.' W is secured to the cross-bar \Y, which extends on top of all. the lovers, and is su 'iported thereon by the crank-arms ll upon its ends, so as to rise and fall.

3' is a series of three serrated registeringwheelsloosely jou rnaled upon a shall; I), which is secured transversely in the upper portion of the frame. These wheels (mgagc with the serrated rollers T, T, and T and have secured to them the drums Y, Y, and Y, respectively, on which the :innounts to be regis tered are numerically placed in the usual manner.

Z are a like series of registeririg-wheels loosely journaled upon a transverse shaft: c, and these wheels are n-ovided with similar drums Z, Z and 7f, circun'iltn'entiallynumbored and dividcd,as in theusual. manner, to display the registered amount.

The registering-wheels Y and Z are arranged in pairs, each. registcring-wheel Y being provided with a stud. (l, which at each revolution of the wheels strikes against the upper end of a vibratin pawl c, and thereby causes a dog pivotally secured to the upper end of said pawl to turn the companion wheel Z one notch. A suitable detent g on each registering-wheel Z prevents any aeci dental displacement. A. s n'ing It returns the pawl (2 into its normal. position, in which it rests against a set-scrmv l, which is adjustably secured in a cross-bar t, which is provided with suitable slots in which the pawls e are guided. inv their movement Suitable windows X X are placed in the outer casing for the display ol. the tablet s and for the reading of the register-ing-wheels by a person standing in front of tlmdevice, and, it necessary for accurate reading, a suitable index may be placed upon the windmvs ol' the registering-witeels.

The parts being etmstructed and arranged as shown and descrilmd, they are intended to operate in the following manner: llydepress- .ing any one oi. the keys E or Il the lever actuated. thereby will. cause the pair oi. sup- )orting-bars to rise with the rear end of such lever. The rear or indicating supporting-bar, which carries an index-tablet, is lil'ted. up to bring its rearward projection ll above the swinging bar M sul'licicnlly high to enable said n'ojection L to pass by and retain its SLlPIlOlillllg-l'Otl in an elevated position after the key is released by the opi'nator. The tablet displayed by the supportingba r is thus held in 'an elevated positionv corresl'lomli ng to the elevated position of the stationary zero tablets and in front of one of them. .It' it be longs to the right-hand group of levers, it is displayed. in front of the right-hand '/.erotablet and indicates cents. ll. it; belongs "to the central. group of levers, it rises in front of the central Zero-tablet and .imlicat s dimes, and if it belongs to the lel't-intnd group of lovers it rises in front of the lelt-haml zm'odabh-t and indicates dollars. its value in every instance corresponds with the number ol the key of i.. actuating-lever. Thus before any amount is indicated the zero-tablets alone appear in sight; but it a key is struck a Illllmerical. tablet correspom'ling to the number of the key struck will rise in front of one of IIO the tablets, and by its relative position in relation to the stationary zero-tablets will indicate the monetary value of the number. At the same time with the indicating supporting-bar the registering supporting-bar P of the lever struck is also raised, and by the engagement of its rack-pawl Q with one of the rollers T, T, and T will impart to the latter a rotary movement of the proper degree to revolve its respective registering-drum and to display in the window a number corresponding to the number of the key struck, its

monetary value being indicated by its position in relation to the indicating-tablets, as the indicating-wheels are correspondingly grouped with the indicating-tablets. If two of the keys, each in different groups, are struck, an amount represented by two numerals will be registered; and if three keys, each in a different group, are struck an amount indicated by three numerals will be indicated, and simultaneously with each indication the respective registering-wheel will register a like amount. It will be seen that every time one of the keys is struck the striker WV is uplifted by its connection with the cross-bar WV, which lies on top of all the lovers, and as the inclined head of the striker \V' strikes against the knocker before the lug L of any rising supporting-rod H reaches the swinging bar M any one of the supporting rods which may happen to be engaged thereon is released and drops by its gravity before a new one is engaged, while at the same time the lug L of a rising supporting-rod is free to pass the swinging bar and is engaged thereon, as the swinging cross-bar quickly returns to its normal position.

Thus every time an operation is performed the old indicating-tablets for the previous amount will drop out of the way and the registering -wheels will simply add the new amount to the amount previously registered.

Vhenever one of the registering-wheels Y completes one revolution-that is, when it has registered to J9it will turn its companion registeringwheel one notch. Thus while the registering-drum Y counts the cents the registering-drum Z represents for each division or notch of its actuating-wheel Z one hundred cents. In like manner the register ing-drum Y counts dimes, while the registering drum Z represents one hundred dimes-that is, ten dollars-for each division or notch of its actuating-wheel Z. The amount registered by the machine can thus be readily read off and computed from the registering-wheels, and at the same time a very large amount may be registered before any necessity arises for setting the registering-wheels back to zero- 5m operation which is easily performed by turning the registering-wheels backward by hand.

I preferably construct underneath the machine a till controlled by the levers O, and this till I preferably construct as shown in Fi 6 of the drawings,wherein m is a drawer supported by an incline n and held in its closed position by means of a spring-catch 0. At the rear end of the drawer is pivotally secured a curved lever p, the rear arm of which is connected by means of the connecting-rod q with a cross-bar r, resting on top of the lever 0, all so arranged that if any one of the keys is depressed the cross-bar 0' will be lifted up and by its action crowd the till outward until it is disengaged from its spring-catch 0, when the drawer will drop out farther of it's own accord to a sufficient distance to permit access to the money for the purpose of making change or for depositing money. In push ing the drawer backward it is automatically locked by the spring-catch O.

The particular advantages of my construction are that it requires but little power to operate the device, as I have dispensed with the use of springs as much as possible, which are liable to become inoperative and introduce a large amount of friction. Thus it requires, for instance, but very little force to operate the swinging bar M, the weight of which is suspended so as to give the bar just a slight tendency to maintain its normal po sition by the action of its gravity, and this is supplemented by a light spring 0, which returns it quickly to its normal position if swung backward, while a suitable stop 0' pre Vents it from being swung too far.

By providing the striker with an inclined head it will actuate the knocker with a quick movement, and its shoulder W, below such inclined head, will instantly release the crossbar V of the knocker, and by engaging thereon allow the supporting-rod WV to drop back quickly in advance of the striker under the action of the gravity of the parts, and allow the spring 0 to return the knocker to its normal position without being interfered with by the striker, which latter is free to move backward until it engages itself from the cross-bar WV and drops of its own accord under the action of its weight and that of the parallel rods as soon as it can do so. The striker is retained in its normal position by the parallel rods which are arrested at right angles to the bar by a suitable stop.

The knocker is constructed and suspended in such a manner as to allow its gravity to maintain its normal position and to require but little power to do its work. The same advantage is obtained for the rack-pawls Q. As soon as the upward movement of any supporting-rod is completed, it is free to fall by its own gravity with little or no friction, and thereby frees the rack-pawl, which returns into normal position by its own gravity and IIO with such little friction 011 the rollers T, T, v

and T that a light spring can prevent any accidental movement. At the same time the registering rollers are actuated by a positive movement, and which can be regulated by the set-screws V to any decided degree of nicety.

The whole construction of the device is very simple and. includes but relatively few parts,

which allows ot' the device being manufactured economically and not liable to get out of order.
